I created developer account and try to access adobe sign console using "https://secure.adobesign.com/public/login" . I'm automatically redirected to: "https://acrobat.adobe.com/link/home/"

Hello,
I already tried registering several days ago, using https://www.adobe.com/acrobat/business/developer-form.html, however received this response: 
 

I used email from my organisation, the same email I’m using in this forum. (you can check web page of this organisation using domain from my email).

So, my email is basically blocked. I cannot access Acrobat Sign console, cannot register for the access, cannot delete current account.

I know the workaround is using different email, but I need to use this exact business email from my organisation.
